5/5

I used A Greener Alternative Ltd to upgrade my heating system from a gas boiler to Air Source Heat Pump, partially funded by the £7.5K government grant. The work was what I would consider to be extensive, as the heating system was relocated from an upstairs boiler cupboard to under the stairs, with upgrades to the plumbing & electrics, including a new consumer unit. I chose this company due to their great reviews & excellent customer service on the phone when I initiated contact. Every person I spoke to was professional, knowledgeable & just really nice. Huge thanks to Khalid, Ellie, Simon & Oli, who looked after me from start to finish. The whole upgrade was done in just over a week, ready for the rest of the house renovation to continue & the work was immaculate. My builder also commented on how nice the installers were. Really chuffed. Thanks for making this part of the renovation super easy & stress-free!

AGE installed our Heat Pump in 2019 and continue to service it. It has worked without fail and to our satisfaction throughout that time. I have been able to recommend them to friends, also for Heat Pumps, and those that have gone forward with installation by AGE are delighted. A strongly recommended, reliable and highly competent company with great staff.

I strongly recommend A Greener Alternative Ltd, that provided me with an Outstanding service in fixing my Air Source system, which stopped working during the recent cold period leaving me without any hot water / central heating. Upon reporting the fault an engineer attended my home within 6 hours and promptly diagnosed the fault, requiring a new flow control part (provided by Samsung). The Service Manager, Andrea, made urgent arrangements for the part to be delivered to my home and for the engineer to be available to fit the part and recommission the system. She kept me informed at every stage and demonstrated real care and went 'the extra mile' to ensure everything was done with urgency (even phoning me when not in the office to keep me updated). l was invoiced a fair sum for the services provided. I would not hesitate to recommend this company who offer outstanding customer services and whose engineers have a very good grasp of this complicated technology that offers 'green solutions'. My thanks go to the whole team but Andrea, and the engineers Lee and Oliver were superstars !!!! Best wishes John - West Sussex

Have used A Greener Alternative for the past few years for my Biomass Boiler. Andrea has always managed to fit us in and Lee has been a fantastic engineer. Thank you very much, you have saved us on many occasions.

Finally we have a Heat Pump

A Greener Alternative recently fitted a new heat pump to our home in Southwater. The team were great & the system not only looks amazing it is very efficient. We have a lovely warm home & a much lower electric bill Thank you for doing a great job :-)

A Greener Alternative - NIBI GSHP replacement

A Greener Alternative have serviced & maintained our original NIBI (2007) GSHP for the last 7 years So we contacted them as soon as it 'self destructed' on new years eve. We discussed the issue & with their experience decided to uprate & install a new NIBI. Over a further 3 weeks they fitted us in, stripped out the old one, installed the new one, re-connected the installed elements, tested & handed it over. Warm again, no drama. A pleasure to have on site, thank you 'A Greener Alternative'!

A Greener Alternative. (There isn't another.)

Simon & his team did an exemplary job when installing my heat pump. They are professional, courteous and consummate experts in their field. They worked diligently to get my complicated underfloor heating system in order. Whenever I've had the odd issue Simon responds immediately and with a positive solution. I couldn't recommend 'A Greener Alternative' highly enough. Thank you guys!
